they run GC/MS if initial come positive or if the company order the test pay for, for example if the test is for job. If the lab is certified will use this standard.
btw if you look for real answer ,morning urine have the highest concentration, ..so go to take your test at the evening,
oh thank you very much for the quick reply just the info i was looking for, ok so there is no difference between faint or bright line that is reasuring and also would make sense since no matter how many times I do the 25ng test it always comes up with the faint line sometimes more bright and sometimes less seems almost random but never as clear as the control. if the line intensity was indication of level of thc then it should have gotten brighter over this week.

Anyway yes I tested my morning urine 1 week ago with 25ng which was negative so hopefuly now 1 week later I am below 15ng that you mentioned was the cutoff for confirmatory test.

The thing that worries me is the fact that I have been forced to be inactive due to my deskjob and wish i knew if i have below 15ng right now you never know lab to lab perhaps their reutine is to do the gc/ms on each test.

what do you think asuming i had 24.9999 1 week ago with half life being what it is can i be below 15ng right now?

sorry I just realized i am ranting lack of sleep due to stress over this does that to you, I will stop now and once again thank you for the info.
